| Abstract: | The effects of different factors on xylanase production by Streptomyces olivaceoviridis E-86 were studied under shake flask conditions. The best initial pH value of growth medium for xylanase production was pH 6.0. Corn cob xylan and beef peptone were the best C source and N source, respectively. The enzyme activity was doubled by addition of 1.5% (v/v) Tween-80 in the medium. By the combination of the above variables, the highest xylanase activity obtained was 1653 U/ml which is the highest ever reported from Streptomyces sp. |
